Yeah, I just noticed that about an hour ago, although it's still gonna be pretty hard to beat three bots with zero help. Maybe when I unlock that guy that can shoot the laser beam, it'll be easier. Or I can just wait until I find at least one other person, that should make it a lot easier.
Does anyone know if practice mode will unlock the trophy though?
